| 摘 要： | 根据巷道顶板的受力状况,提出了巷道顶板的“自稳隐形拱”概念,并利用大型软件FLAC对开挖后的巷道进行了数值模拟,推导出了自稳隐形拱与极限自稳隐形拱的曲线方程。通过改变巷道断面形状、加帮部锚杆和顶板锚杆,可以改变自稳隐形拱和极限自稳隐形拱的曲线位置,为支护设计提供了依据。

| Abstract: | Based on the mechanical behavior of the roadway roof, a concept of self-stabilized hidden arch of roadway roof was put forward in this paper, numerical simulation was made after excavation of roadway with FLAC software and a curvilinear equation of self -stabilized hidden arch and limit self -stabilized hidden arch was derived. The curve position of self-stabilized hidden arch can be changed by changing the section configuration, adding side and roof bolts. The results are helpful and can provide a basis for support design. |
